Application fl1ed 0ctoher 3, 1912. I Serial No. 723,750.

To all whom it may-concern:

- Be it known that I, Ems D. CLARAGE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State'of Ohio,'have invented new and useful Improvements in Locks for Clutch-Pedals,

of which the following is a specification.

This invention "relates to an improved A further object is-to produce a device of this character which may .be readily and quickly placed in operative position, or re-,

moved from thevehicle if its use is not desired.

A further object is to construct a locking 2 device of the character referred to which may be connected to the vehicle without requiring any change in the construction ofthe latter and withoutmarringrthe vehicle in any manner.

The invention will be hereinafter fully set forth and particularly pointed out in the claims. g

In the accompanying drawing :Figure '1 is a perspective view illustrating a portion of an automobile or motor vehicle with my invent-ion applied thereto, the parts being shown in locked position. Fig. 2 is a similar view with the parts unlocked. Fig. 3 is an enlarged plan view of my improved locking device, parts being shown in section. Fig.4 is a longitudinal sectional view illustrating the supporting block. Fig. 5

-is a transverse sectional view illustrating a slightmodificat-i on of the supporting block.

Referring to ,the "drawing, 10 designates a portion of the floor or'platform, and 11 the dash of an automobile or motor vehicle which may be of any suitable or preferred type, the steering column 12 being secured to the'dash 11 by bolts 13 in the usual way. The clutch pedal 14. is of the usual or preferred type. a

My improved locking. device comprises a locking bar or plate 20 provided at one endwith a pivot stud 21, the other end being provided with a laterally extended fork 22 constructed to embrace the shank of the clutch pedal 14. Pivotally mounted on one In practice, I left'hand bolt 13 of the steering column and of thearms of the fork 22 is a yoke bar 23 provided with an opening 23' adapted to coincide with a similar opening in the other arm of f'ork'22 to receive the shank of a padlock 24. The-pivot stud is adapted to enter a cylindrical recess 25 in a supporting block -26,- said block being provided with a threaded bolt-like extension 27 carrying a nut 28. The stud 21 is provided with a 1ug28 and the recess 25 is provided with an offset 29 to receive the same, the'lower portion of said recess being enlargedor' cornterbored at 30. prefer to remove the lower substitute therefor'th'e bolt like-extension 27 of the block 26, the nut 28 being'screw'ed up tight after the substitutionhasbeen made,

and the bolt riveted thereover. After the Pa'tcnted July '7, 19.14.

block has been secured in. position the stud 21 is inserted in the recess 25 until the lug 28 passes into the .counterbored portion 30,

, whereupon the bar 20 may be freelyswu'ng in either direction. When it: is desired to lock'the pedal 14 the yoke bar 23 is swung to one side and the clutch pedal moved to an intermediate position; The bar 20 is then swung on the stud 21 so as to cause the fork 22 fto' engage the shank of said pedaL' The yoke bar 23 is then swung into a position to span the fork 22 and a padlock slipped through the opening 23 and the corresponding opening in the fork 22. The pedal is thereby positively and securely locked against any movement whatever, and as long as the parts are in the positions thus described it" will impossible to start the vehicle or operate it in any manner, even though the :engine were started. When in the locked position it is impossible to remove thestud 21 from the block 26 as the lug 28 is out of register with the offset- 29. WVhen it is desired to unlock the pedal, the padlock is removed in the ordinary manner and the yoke bar swung to one side, permit-t-ing thelocking bar to be swung on the pivot stud 2i. Thusthe pedal is left free for necessary or desired manipulation. The locking bar may be retained in the unlocked position by means of a suitable spring catch or detent 31, or it may be entirely removed from the supporting block 26, as may be desired.

In lieu of forming the block 26 with a no the block is provided with a threaded recess 32 which is engaged by a bolt 33. To secure [the block in position, the lower left hand iibolt 13 of the steering column is re moved; the bolt 33 substituted therefor, being passed back from the' front of the dash-11. The block 26 is then screwed up on'said bolt, serving as a nut therefor. The locking bar is then applied in the manner hereinbefore described. It will be noted in this connection that when the locking-bar 20 is engaged with clutch pedal 14 it will be .impossible to remove the block 26 by unscrewing.

Having. thus explained the nature of my invention and described an operative manner of constructing and using the same, al-

though without attempting to set forth all of the forms in which it may be made or all of the forms of its use, what I claim is z- 1. A pedal lock for motor vehicles comprisin a supporting block, and a locking bar having a pivotstud rigidly secured to one end thereof and reinovably engaging said supporting block, whereby the locking bar is pivotallysupported, said supporting block and pivot stud being provided with complement-a1 interlocklng means.

2. A pedal lock for motor vehicles comprising a. supporting block provided with P recess having an offset portion and a eounterbored portion, and a locking bar having E lison D. CLARAGE.
